This valve is kept closed by the weight, and also by the pressure-inthe boiler, which will be about onduitv 14,- l

voperation p 'the usual pressure used in such a system. 110

As the water rises in the drain chamber, it will operate the Boat, forcing the same vertically up the rodn 8, until it contacts the stop 11, and thus raises the rod, closing the-openingin the top of the casing by means of the stopper 10. Up to this time, the air has been allowed to escape through the openings `in the two yokes 5 and 21, and through the opening in the top of the chamber. The air outlet now having been closed, the pressure in the chamber will be built up until it is more than the pressure in the boiler, by reason of the air which is being pumped into the chamber by the pump 3. The pressure will build up to a point at which it is suiiicient to overcome the boiler pressure, and also to overcome the pressure exerted by the Weight 17 on the valve 16. If upon closingof the air outlet the pressure in the chamber does not quickly rise high enough to o vercome the pressure on valve 16, the inlet opening will be nsealed to further entrance of gas and the incoming liquid will compress vthe gas above it suiiciently toproduce a pressure greater than that on valve 16. This valve will then be forced open, but the valve in the top of the `chamber will still be closed,

and the pressure will continue substantially constant until the water has drained out ot' the chamber into the boiler, by reason of the constant incoming supply of air and wal ter from the pump. The float will, of course,

follow the level of the liquid, and upon reaching the lower stop 12, its weight will Jforce the rod 8 downward,thus opening the Valve in the top of the chamber, and permitting the escape of the air. The operation will then be repeated, and is, of course, lautomatic at all times.

The advantagesof the present construction are its simplicity and its ready attachment to the boiler' and to the pump. There is nothing to get out of order, and no com.- plicated valves have to be installed to permit the escape of either the air or the water.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism .herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and dis'- tinctly claim as my invention l 1. The combination of a liquid drain chamber, having an inlet opening directed downwardly and disposed intermediate the top and bottom of the casing and an outlet opening for liquids; valve means normally closing said liquid outlet opening; a valve in said gas opening; a float operable by the liquid level in said chamber and adapted upon operation to close said gas opening valve, thereby causing an increase in pressure due to the incoming liow of mixed liquid and gaseous fluid, said liquid opening valve being adapted to operate at a predetermined pressure; said inlet opening being so disposedthat it is sealed upon the rise in liquid level in said chamber, thereby preventing further admission of gaseous iuid.

2. The combination of a liquid drain chamber, having an inlet opening directed downwardly and disposed intermediate the top and bottom of the casing; an outlet opening for gas disposed in the top of said chamber and an outlet opening for liquids; valve means normally closing said liquid opening; a stopper having a rod attached thereto and adapted to close said gas opening; av float slidably mounted on said rod, two stops mounted one' at the upper and one at the lower end of said rod; said ilo-at being adapted upon the rising of the liquid level in said chamber to contact said r pper stop,

thereby raising said rod; said gas opening being thereby closed and thus causing an increase in the pressure in said chamber due to the incoming liquid suiiicient to open.

said liquid opening valve, said float being adapted upon being lowered to contact said lower stop, thereby'opening said gas valve; said inlet opening being so disposed that it is sealed upon the rise in liquid level in said chamber, thereby preventing further admission of gaseous fluid thereto.

3. The combination of a liquid drain chamber, having an inlet opening for mixed,

liquid and gaseous fluids, an outlet opening for gas and an outlet opening for liquids;

valve means normally closing said liquid outlet opening; a Valve in said gas opening; a float operable by the liquid level in said chamber and adapted upon operation to close said gas opening valve, thereby causing an increase of pressure in said chamber due to the incoming iiow of mixed, liquid and gaseous fluid, said liquid opening valve being adapted to operate at a predetermined pressure; and means adapted to vary the operating pressure required for said lastf named valve.
